Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of prefabricated cabin cable connection structures, and more specifically, to a prefabricated cabin cable connection structure. Background Technology

[0002] In fields such as power systems and data centers, prefabricated cabins have become the core carrier for outdoor equipment integration due to their advantages of convenient installation and high modularity. The cable connection structure within the cabin is a crucial link in ensuring stable power transmission and signal interaction. Prefabricated cabins are mostly used in outdoor open-air environments and must withstand long-term exposure to external influences such as wind, rain, and temperature variations, placing stringent requirements on the protective performance (waterproof, dustproof, and corrosion-resistant) and fixing reliability of cable connections. However, current cable connection and fixing methods for prefabricated cabins have significant drawbacks: poor protective effect and susceptibility to water leakage, seriously threatening the safe operation of equipment within the cabin and increasing maintenance costs. Traditional prefabricated cable connections often employ a simple structure of sealing rings and metal sleeves, with initial tightening only using bolts. Over time, the sealing rings are prone to elasticity loss due to aging and temperature changes, leading to increased sealing gaps. Outdoor rainwater and dew can easily seep into the compartment through these gaps, causing water accumulation. Water leakage not only damages the cable insulation, causing short circuits and tripping, but also corrodes the wiring terminals of equipment inside the compartment, shortening equipment lifespan. Therefore, developing a prefabricated cable connection structure with excellent protective performance and that can prevent water leakage has become an urgent need for the industry to ensure the stable operation of equipment. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a prefabricated cabin cable connection structure, which solves the technical problem of poor protection and easy water leakage in the prior art, which seriously threatens the safe operation of equipment inside the cabin.

[0022] like Figures 1-3 As shown, it illustrates a prefabricated cabin cable connection structure according to an embodiment of the present disclosure, including: The filling and sealing sleeve 1 and several protective tubes 2 are connected to each other, and one of the protective tubes 2 is connected to one end of the filling and sealing sleeve 1; External cable 3, internal cable 4, and docking assembly 5, wherein the external cable 3 and the internal cable 4 are both connected to the filling and sealing sleeve 1, and the docking assembly 5 is disposed in the filling and sealing sleeve 1; A protective fixing component 6 is disposed on the protective tube 2; The docking assembly 5 includes a sealing core 5-1, which is disposed inside the sealing sleeve. Several conductive blocks 5-2 are disposed inside the sealing core 5-1 and fixed inside the filling sealing sleeve 1. An external connector 5-3 and an internal connector 5-4 are respectively inserted into both ends of the filling sealing sleeve 1. The external connector 5-3 and the internal connector 5-4 are respectively connected to the external cable 3 and the internal cable 4. A compression sleeve 5-5 is inserted into both ends of the filling sealing sleeve 1. One of the compression sleeves 5-5 is connected to one end of the protective tube 2. A sleeve layer 5-6 is disposed around the outer surface of the compression sleeve 5-5 and is fitted onto both ends of the filling sealing sleeve 1. An outer protective sleeve 5-7 is rotatably fitted onto the compression sleeve 5-5 and the sleeve layer 5-6, and the outer protective sleeve 5-7 is sealed and fitted to the sleeve layer 5-6. The outer protective sleeve 5-7 is threadedly connected to the outer surface of the filling sealing sleeve 1.

[0023] In some examples, in order to achieve a firm connection and all-round sealing between the external cable 3 and the internal cable 4, prevent external moisture and dust from entering the connection part and causing short circuits or poor contact, ensure the stability of cable transmission, and adapt to the use requirements of prefabricated cabins in outdoor or humid environments, a docking component 5 is designed. The sealing core 5-1 inside the filling sealing sleeve 1 of this component is made of elastic sealing material (such as rubber or silicone), which fits tightly against the inner wall of the filling sealing sleeve 1 and can fill the internal gap of the filling sealing sleeve 1 to form the first sealing barrier.

[0024] Several conductive blocks 5-2 inside the sealing core 5-1 are fixed inside the filling sealing sleeve 1 by bolts. They are made of metal with excellent conductivity. The conductors of the external cable 3 and the internal cable 4 can be connected to the two ends of the conductive blocks 5-2 respectively to achieve stable transmission of current or signal. The fixing structure of the conductive blocks 5-2 prevents the cable conductors from becoming loose due to vibration.

[0025] The external connector 5-3 and the internal connector 5-4 inserted into both ends of the filling and sealing sleeve 1 are tightly fitted to the insulation layers of the external cable 3 and the internal cable 4, respectively. This not only positions the cable but also isolates the conductor from direct contact with the outside world. The compression sleeves 5-5 inside both ends of the filling and sealing sleeve 1 are fixed to the filling and sealing sleeve 1 by interference fit or threaded connection. One of the compression sleeves 5-5 is connected to one end of the protective tube 2, which can form a continuous protective channel between the protective tube 2 and the filling and sealing sleeve 1. At the same time, the compression sleeve 5-5 can squeeze and seal both ends of the filling and sealing sleeve 1, enhancing the end sealing performance.

[0026] The sleeve layer 5-6 around the outer surface of the compression sleeve 5-5 is made of wear-resistant and corrosion-resistant material. It is fitted around both ends of the filling and sealing sleeve 1 to protect the ends of the filling and sealing sleeve 1 from external impact or environmental erosion. The outer protective sleeve 5-7, which is rotated around the sleeve layer 5-6, is sealed and fitted with the sleeve layer 5-6 (e.g., with a sealing ring). The outer protective sleeve 5-7 is connected to the outer surface of the filling and sealing sleeve 1 by a threaded connection. Rotating the outer protective sleeve 5-7 can further compress the sleeve layer 5-5 and the compression sleeve 5-5, making the sealing parts fit more tightly and forming a multi-layer sealing structure to completely block the intrusion path of external impurities. During operation, connect the conductor of the external cable 3 to the external connector 5-3 and insert it into one end of the filling sealing sleeve 1. Connect the conductor of the internal cable 4 to the internal connector 5-4 and insert it into the other end, ensuring that the conductor is in contact with the conductive block 5-2. Install the clamping sleeve 5-5 and the sleeve layer 5-6, and rotate the outer protective sleeve 5-7 to ensure that all components fit tightly. The sealing core 5-1 fills the gaps. The multi-layer sealing and stable connection work together to achieve a firm and sealed connection of the cable, ensuring safe transmission.

[0027] like Figures 1-3 As shown in the figure, the protective fixing component 6 proposed in this embodiment includes a pair of fixing plates 6-1. Each fixing plate 6-1 has a pair of protrusions 6-2 on its surface. A sleeve 6-3 is fitted around the protrusions 6-2. The sleeve 6-3 and the protrusions 6-2 are fixedly connected by bolts. The protective tube 2 located in the middle section is fitted between the protrusions 6-2 and the sleeve 6-3. The protective tubes 2 are fixedly connected by flanges and bolts. The internal cable 4 is inserted into the protective tube 2.

[0028] In some examples, in order to achieve full protection and fixation of the internal cable 4, prevent the internal cable 4 from being damaged by external pulling, vibration or environmental erosion, and ensure the safety and stability of the cable when it is laid in the prefabricated cabin or outdoors, a protective fixing component 6 is designed. This component includes a pair of fixing plates 6-1 that are fixed to the inner wall of the prefabricated cabin or the supporting structure by expansion bolts or welding, providing a stable installation base for the entire protective fixing component 6.

[0029] A pair of protrusions 6-2 on the surface of the fixing plate 6-1 are integrally formed or welded and are symmetrically distributed. They can cooperate with the sleeve 6-3 to form a clamping space for the protective tube 2. The surface of the protrusions 6-2 can be provided with anti-slip textures or rubber pads to enhance the friction with the protective tube 2 and prevent the protective tube 2 from sliding.

[0030] The sleeve 6-3, which is fitted outside the protrusion 6-2, is fixedly connected to the protrusion 6-2 by bolts. The inner wall of the sleeve 6-3 fits tightly against the outer surface of the protective tube 2, firmly clamping the protective tube 2 located in the middle section between the protrusion 6-2 and the sleeve 6-3. This achieves segmented fixation of the protective tube 2 and prevents the protective tube 2 from sagging or shifting due to its own weight or cable pulling. It is especially suitable for cable laying scenarios with longer distances.

[0031] The protective pipes 2 are fixedly connected by flanges and bolts. The flange connection facilitates the disassembly and extension of the protective pipes 2. At the same time, a sealing gasket can be installed at the flange connection to enhance the sealing between the protective pipes 2 and prevent moisture and dust from entering the protective pipe 2 and contacting the internal cable 4. The internal cable 4 is inserted inside the protective pipe 2. The protective pipe 2 is made of high-strength, corrosion-resistant materials (such as PVC pipe or metal corrugated pipe), which can provide physical protection for the internal cable 4, isolating it from damage caused by external mechanical impact, ultraviolet radiation, chemical corrosion and other factors. The segmented fixed protective pipe 2 can limit the range of motion of the internal cable 4, prevent the cable from being excessively bent inside the protective pipe 2, which would lead to damage to the insulation layer, and at the same time prevent the cable from being worn due to vibration.

[0032] During operation, the fixing plate 6-1 is fixed according to the laying path of the internal cable 4. The middle section of the protective pipe 2 is clamped between the protrusion 6-2 and the sleeve 6-3. The sections of the protective pipe 2 are connected by flanges. After the internal cable 4 passes through the protective pipe 2, it is connected to the docking assembly 5. The segmented fixing ensures the stability of the protective pipe 2, isolates the protective pipe 2 from external damage, and the flange connection ensures sealing and convenient disassembly and assembly. All components work together to achieve all-round protection for the internal cable 4, which meets the requirements for long-term safe operation of prefabricated cabin cables.

[0033] For example, such as Figure 3 As shown, the inner diameter of the sleeve 6-3 is smaller than the outer diameter of the protective tube 2.

[0034] In some examples, the inner diameter of the sleeve 6-3 is smaller than the outer diameter of the protective tube 2. This design creates an interference fit between the sleeve 6-3 and the protective tube 2. When the sleeve 6-3 is fitted onto the outside of the protective tube 2, it generates a radial clamping force, significantly enhancing the tightness of the fit. Combined with the supporting effect of the protrusion 6-2, the protective tube 2 can be firmly fixed between the sleeve 6-3 and the protrusion 6-2, preventing axial slippage or radial displacement of the protective tube 2 due to vibration or external pulling. The interference fit also fills in minor unevenness on the surface of the protective tube 2, reducing the gap between the protective tube 2 and the sleeve 6-3, further improving the stability of the fixation. This is particularly suitable for prefabricated cabin scenarios that are subject to long-term vibration, ensuring the stable position of the internal cable 4 within the protective tube 2 and preventing cable wear due to displacement of the protective tube 2.

[0035] For example, such as Figure 1 As shown, both the upper and lower protective tubes 2 have an L-shaped structure.

[0036] In some examples, both the upper and lower protective pipes 2 are L-shaped. This structure can flexibly adapt to the turning and laying requirements of cables in the prefabricated compartment, eliminating the need for additional elbow connectors, reducing the number of connection nodes, and lowering the risk of moisture and dust intrusion from the connection nodes. The right-angle bend design of the L-shaped protective pipe 2 can fit against the inner wall of the prefabricated compartment or the corner of the equipment, making full use of limited space and avoiding excessive bending during cable laying. At the same time, the integrated L-shaped structure is stronger than spliced ​​elbows, and can better resist external mechanical impacts, ensuring that the internal cable 4 is reliably protected at the bend, adapting to the complex wiring environment inside the prefabricated compartment.

[0037] For example, such as Figure 2 As shown, the cross-section of the filling sealing sleeve 1 has an H-shaped structure.

[0038] In some examples, the cross-section of the filling seal sleeve 1 is H-shaped. This structure creates symmetrical receiving cavities at both ends of the filling seal sleeve 1, which are respectively adapted to the installation of the outer connector 5-3 and the inner connector 5-4, ensuring that the sealing structures at both ends are symmetrical and consistent, thus improving the overall sealing stability. The raised portion in the middle of the H-shape can enhance the structural strength of the filling seal sleeve 1, preventing it from deforming due to compression when the outer protective sleeve 5-7 is installed. At the same time, the raised portion in the middle can also provide more sufficient installation space for the sealing core 5-1, allowing the sealing core 5-1 to more fully fill the internal gap of the filling seal sleeve 1, further optimizing the sealing effect.

[0039] In practical use: Insert the inner cable 4 into several protective tubes 2, and connect the protective tubes 2 to each other using flanges and bolts. One of the protective tubes 2 is connected to the compression sleeve 5-5 at one end of the filling sealing sleeve 1. Connect the outer cable 3 to the outer connector 5-3 and the inner cable 4 to the inner connector 5-4, inserting them into both ends of the filling sealing sleeve 1, ensuring that the cable conductor is in contact with the conductive block 5-2 inside the sealing core 5-1. Sleeves 5-6 are fitted onto both ends of the filling sealing sleeve 1, and the outer protective sleeve 5-7 is rotated to make it threaded into the filling sealing sleeve 1, forming a seal with the compression sleeve 5-5. Next, fix the protective fixing assembly 6, install the fixing plate 6-1 in a suitable position in the prefabricated cabin, place the middle section protective tube 2 on the protrusion 6-2 of the fixing plate 6-1, and then fix the sleeve bracket 6-3 after fitting it onto the protrusion 6-2 with bolts, so that the protective tube 2 is securely clamped between the protrusion 6-2 and the sleeve bracket 6-3. The entire process utilizes multi-layer sealing and segmented fixing to achieve cable protection and stable connection, making it suitable for outdoor use in prefabricated cabins.
